I have Penelo set up to cast Libra and Ally: Any > Protectga. I haven't felt the need to do the same with Shell. Anyone who can run Bubble casts it on themselves.

My other buffs/debuffs are situational: I'll turn on Ashe's Ally: Any > Haste gambit when opening up a fight with bosses/espers/marks, then Slow the boss after Penelo hits it with Dispelga to wipe its buffs if necessary. I also have gambits using buffs to counter debuffs if Esuna isn't good enough. Haste on Slow, Regen on Sap, etc.

Not much. Vaan and Balthier are my rotating party leader, so they have Self>Libra. I just put Bubble on Fran. I had Haste on Fran, but it's a bit of a drain. She has more MP now, so maybe I'll try it again. For now, it's just Ally: Slow> Haste.

Are you guys playing Active? I am mostly now, but I find the combat too fast to go Active during harder Hunts.

Fran and Balthier both have high priority on Ally:any > Raise, so in the cases where Ashe goes down she's often back to life before the text comes up asking me to switch party leaders. Ashe herself has ally:any > Phoenix down which is even faster than raise for getting people back on their feet.

In terms of attack gambits for general use, Ashe and Fran both have 'lowest HP > attack' while Balthier has 'foe:100% > attack' first for those times where Fran gets stuck trying to steal from someone with her steal gambit and not contributing.

I think fire spells might be the only elemental magic that can be boosted this way, so this combination might be worth running against any large enemy group not strong against fire.

I'm also constantly running at 2x speed unless I'm fighting a boss/mark/esper or, very rarely, one of those rare specimens in the bestiary which are usually stronger than average, or if I accidentally pull aggro on an elemental.

Big batch of fresh marks on the board after getting back from Giruvegan. A few with cheevos attached too. 'til now I've finished all of 'em except Tricky and Gilgamesh. So I should put on some podcasts and go hunting while I've got a guest in the party.

Shear is a great ability (lowers enemy magic resist), Ashe is throwing out 10k nukes like she's going out of business. Tried the oil trick, seems a lot of hunts are just immune to it which is sad.

I'm also impressed that if I can hit/kill at least 2 enemies with Ashe's magic she has a net gain of MP. The trickiest hunt I had today was one in the Necrohol who just spammed gravity. It was mostly trouble because I ran into it with my backup party who are all melee and so all getting hit by the spells. Eventually managed to trade them out as they died (before my revive gambits put them back up) and then it became a cakewalk since Fran and Balthier stand so far back with their bow/gun.

Had one hunt (Overlord) with a companion along, apparently this companion was immune to Bubble which was fun to learn after Fran got stuck in a buff loop on him.
